*sigh* Still, even having read that guide, and knowing the controls, I can not for the life of me keep my players from pretty much cluelessly running around the field, and shooting the ball in all directions except the goal.
I felt the same way once, but gradually got use to it.
I play with a finger on the Shift key and one on the mouse. I do not use any other keys.
You can either take the ball from the start or let the opposition take it, then intercept it ( move your player into the other to grab ball and keep going).
If you lose the ball - leave the player and take another player from further down the field to intercept and gather the ball. Use Shift to return players to position, so you keep a clear field to play in.
While in practice, don't worry so much about scoring but get use to moving 1 player around the field and keeping the ball. If you see the opposition coming, then turn in another direction then turn back to your original route - the ball is only lost if they bump into you.
Once you can control one player around the field, start leaving 1 player near the goal and using him to pass the ball to.
Remember shift is your friend. Being too cluttered is not good.
Good luck.
